Product Description
1. Concentric ventilation butterfly valve realizes medium flow and flow regulation in pipeline through 90 degree rotation of disc around central shaft. It features light weight structure and fast opening and closing action.
2. Disc and seat adopt concentric structural design with sensitive rotation stroke and fast response.
3. It has light overall weight and simple construction. It is suitable for flow and pressure control of air and other gases under low pressure condition, and also applicable for high temperature gas service.
4. The valve is widely used in ventilation dedusting, flue gas treatment, flue gas desulfurization, dedusting system, HVAC pipeline and environmental protection projects. It serves as air volume isolation and regulating device for pipelines carrying air, flue gas and dust laden gas. It is especially suitable for large size and low pressure ventilation pipeline systems.
